Synthesis of novel, orthogonally protected multifunctional amino acids
摘要:
Two synthetic strategies for the generation of differentially protected, chiral tri-amino acids have been developed. The first strategy is based on the reductive amination of a serine-derived oxazolidine aldehyde with mono N-protected ethylenediamine. The second approach involves reductive alkylation of an asparagine-derived N-protected diaminopropionate with an N-protected glycinal. The newly generated secondary amine functionality is derivatised to furnish structurally diverse molecules, (C) 1999 Elsevier Science Ltd. All rights reserved.

The synthesis of a tris-Boc tri-amino acid and its utility in the generation of dendrimers as inert scaffolds on solid supports is described. These high loading amine functionalized resins were successfully used in the syntheses of small molecules, (C) 1999 Elsevier Science Ltd. All rights reserved.
